Build a Voice-Powered Accessibility Tool

Описание и применение

Создана простая система преобразования текста в речь с поддержкой кастомных голосов, использующая ElevenLabs и Python.

Задача

People with visual impairments, dyslexia, or motor challenges need a convenient way to consume long text on small screens.

Результат

The workflow produces a functional voice‑powered accessibility tool that converts arbitrary text to speech, supports custom voice cloning, and exposes a minimal web UI for end users.

Рабочий процесс

• Obtain an ElevenLabs API key by signing up and generating a key in the dashboard.
• Store the key in an environment variable (ELEVENLABS_API_KEY).
• Test the API with a curl request to confirm connectivity and receive a .wav file.
• Create a Python wrapper (tts.py) that sends POST requests to the ElevenLabs TTS endpoint and returns an in‑memory audio buffer.
• Run the wrapper to generate an output.wav file from sample text.
• Upload a short voice sample (≈30 s) to ElevenLabs to clone a custom voice and receive a new voice_id.
• Use the cloned voice_id in subsequent TTS calls to produce personalized speech.
• Deploy a tiny web UI that accepts user text, calls the Python wrapper, and streams the audio to the browser.

Доказательства

If you’ve ever struggled to read a long article on a tiny screen, you know how powerful a good voice interface can be.
